SHAOXING SILICORE TECHNOLOGY CO.,LTD www. Silicore. com. cn CHMC 1-CHIP DEFECTION SYSTEM CD1379CP DESCRIPTION Outline Drawing The CD1379CP consists of a vertical system including function and a horizontal system including an AFC function . It is for use in small size color TV, B/W TV receivers and monitors. FUNCTIONS z Horizontal Section z SYNC separation z Horizontal Oscillators z Horizontal Pre-drivers z Horizontal AFCs z Shunt Regulator(Typical 6.7V) z Vertical Section z Vertical Oscillator z Vertical Pre-drivers z Vertical Output z Fly-back generators FEATURES: z Low Power consumption, direct deflection coil driving capability (Fly-back voltage two times as high supply voltage is supplied during fly-back period only) z Variable circuit of vertical retrace time on chip
